Actually INFO is usually sent out as part of MID_DIALOG. But when the new call comes to A, the IMSServer can send 180 as follows.
SIP/2.0 180 --Waiting for Call-- and if A disconnects, it can automatically connect.

For instance if A and B exist in active dialog. IMS Application server serving A received a new call to A and wishes to inform a waiting tone to A, in the A-B active dialog. Is this possible with method INFO? If yes, what is the content-type and subtype?
